Barclaya.] FLOKA INDICA, 245
rivers. We have, in the observations under the Natural Order, indicated the mor-
phological differences between the structure of the flower of Ngmyhaa and Euryale.
A detailed description of its mode of germination will be found in Roxburgh's * flora
Indica,* according to which, and to Planchon's and our own observations at Kew, the
process is exactly that of Victoria regia, and differs from Nympkaa in the radicle
being even less developed perpendicularly, but sending out short, horizontal, often
branched arms, that perform the office of rootlets to the radicle. The elongating
plumule bears two strictly opposite primary leaves, one of which remains as a subulate
petiole and the other bears a very long linear lamina, with a hastate base, and gives
off adventitious rootlets from its petiole: within the first pair a third is developed
sher.thed in an opposite stipule, which much resembles the vaginate petiole of one of
the second pair of leaflets of NympJusa.
The only known species is also a native of China, where it has been cultivated
for its edible seeds, from time immemorial. Flanchon has made a second species of
this, founded on a description ofJE.ferox, the fruit of which Salisbury describes as
being 80-100-seeded, which is no doubt a misprint for 8-10, the number I find in
the original specimens from which his description was drawn up. The seeds vary
exceedingly in size, from a small pea to a nut, and the starch grains of the albu-
men arc BO minute as to cxliibit the " Brownian motion " under a sufficiently high
power. The testa is always hard and almost bony, and smooth or wrinkled.
The large fruits of this plant are sold in the markets of Eastern Pengal, stripped
of their spiny pericarp; and the seeds are roasted and eaten as food and medicine.
These seeds have been found by Dr. Falconer in tertiary beds of peat near Calcutta,
a district the plant does not now inhabit.

Boyle mentions that the Euryale is found^ but no doubt in a cultivated state, in
the plains near Saharanpur.
